Fix out-of-range color temperatures

Browse Source 
If light.turn_on is invoked with `brightness: 128, color_temp: 500`
for a bulb that supports mired range 154..370 in value range 1..255
the calculated color temperature will be negative.  When the bulb
receives the command it may turn on, but will fail processing the
color_temp operation and will not send a response.

At this point `light.toggle` will have no effect because Home
Assistant is unaware that the bulb is on.

Fix the state by clamping the sent color temperature to the allowed
range.
